The elite crew of iPhone hackers have recommended iPhone 4S and iPad 2 users to update their device to the official iOS 5.0.1 firmware. Now is the time to download, update your iOS device.
You know the drill: Find the official iOS firmware links, download it; connect your iOS device to your computer. Launch iTunes. Restore the firmware. Then, wait — wait till your Apple device is updated to that firmware.
Another relatively easier, perhaps more preferable, way to install iOS 5.0.1 firmware is through OTA. As you probably know this by now, OTA is Over-The-Air update, which eliminates the middleman, our computer and downloads, installs the update right from your iOS device.
Install iOS 5.0.1 OTA: Go to Settings -> General, tap on Software Update. The device will check for iOS update, download and install that firmware. Make sure you are downloading iOS 5.0.1 firmware, if that is what you want.
Upgrading your iPhone 4S or iPad 2 to iOS 5.0.1 firmware not only guards your device from security-related issues but also offers significant improvement. Battery bug fixed, Siri-related changes is carried out, and issues with cloud documents have been resolved with iOS 5.0.1.
Besides this, if you are going to do an untethered jailbreak to your iOS device, you will need to upgrade to iOS 5.0.1 anyway.
If you would prefer to go the iTunes way than Over-The-Air, check out these download links of the official iOS 5.0.1 firmware yanked right out of the Apple server:
